High speed serial ports What is the intended use? I use Digiboard classic 4 and 8 port cards ( I would have to confirm but I believe that is it) for high speed serial data transfer. I cannot confirm that they sustain the high speeds but I believe these cards do ($409 for 4 ports). I also use high speed serial ports that were standard issue in several of our computers. These serial cards do not sustain the higher baud rates. If you observe the data on screen as it downloads you can see an initial high rate and then it tapers off dramatically after 20 seconds +/-.
